New Jersey Department of Environmental Protection, New Jersey Geological SurveyThe Geographic Information System (GIS) point layer, Abandoned Mines of New Jersey contains locations and attributes for abandoned mines. The shapefile has locations for nine types of abandoned mines which are Copper, Graphite, Iron, Lead, Mica, Manganese, Sulfide, Uranium and Zinc. There are 588 abandoned mine locations in the database and they are mapped at a scale of 1:24,000. This updated version of the data has undergone significant changes in two USGS quadrangles since the previous version of this data, dated July 29, 2005, was published. Previously, Bloomsbury, Blairstown, Easton, and High Bridge USGS quadrangles were updated. In this update, field work by geologists was conducted to improve the locational information of the mines in the Franklin and Riegelsville USGS quadrangles. Some of the mines in these quadrangles were located using the global positioning system (GPS). Certain mines in these quadrangles were mapped for the first time and appear in this data but not in the previous version of the data. Some known mine locations in the previous version of the data have been more accurately mapped and the points have been relocated.ArcGIS DynamicMapLayerhttps://hub.arcgis.com/datasets/9064d507ff944c25ab1cad75a24423e4_0engNew Jersey Department of Environmental Protection's (NJDEP) Bureau of GISPublicAbandoned Mines in New Jersey [New Jersey]Web servicesNew JerseyLast Modified: 2025-08-14
